Abstract
A method of manufacture of a liquid crystal display panel is described whereby a fixed number of drops of liquid crystal, or a mixture of liquid crystal and spacers, are dropped at various positions on an electrode face of at least one of a pair of substrates, with the amount of liquid crystal in each of the drops being predetermined to a very high degree of accuracy. One of the substrates is then superposed on the other, under a condition of reduced air pressure, then under a condition of normal atmospheric pressure, mutual lateral position adjustment of the substrates is performed to a high degree of precision.
